Trajectory privacy protection scheme based on differential privacy
Tongxin xuebao, 2021 To solve the problem that the current sampling mechanism and data obfuscation method may raise insufficient data availability and privacy protection, a trajectory privacy protection scheme based on differential privacy was proposed.A new efficient ...

Privacy risks in trajectory data publishing: reconstructing private trajectories from continuous properties [PDF]
, 2008 Location and time information about individuals can be captured through GPS devices, GSM phones, RFID tag readers, and by other similar means. Such data can be pre-processed to obtain trajectories which are sequences of spatio-temporal data points ...

Privacy-preserving trajectory similarity computation method
Tongxin xuebao, 2022 To tackle privacy concerns on user information leakage in trajectory outsourcing services, a privacy-preserving trajectory similarity computation (pTSC) method was proposed.A trajectory outsourcing service provider was enabled to store encrypted ...

Real-world trajectory sharing with local differential privacy [PDF]
Proceedings of the VLDB Endowment, 2021 Sharing trajectories is beneficial for many real-world applications, such as managing disease spread through contact tracing and tailoring public services to a population's travel patterns. However, public concern over privacy and data protection has limited the extent to which this data is shared.

Preserving Trajectory Privacy in Driving Data Release
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 Real-time data transmissions from a vehicle enhance road safety and traffic efficiency by aggregating data in a central server for data analytics. When drivers share their instantaneous vehicular information for a service provider to perform a legitimate task, a curious service provider may also infer private information it has not been authorized for.

Multi-camera trajectory forecasting : pedestrian trajectory prediction in a network of cameras [PDF]
, 2020 We introduce the task of multi-camera trajectory forecasting (MCTF), where the future trajectory of an object is predicted in a network of cameras. Prior works consider forecasting trajectories in a single camera view.

Privacy Preservation in the Publication of Trajectories [PDF]
The Ninth International Conference on Mobile Data Management (mdm 2008), 2008 We study the problem of protecting privacy in the publication of location sequences. Consider a database of trajectories, corresponding to movements of people, captured by their transactions when they use credit or RFID debit cards. We show that, if such trajectories are published exactly (by only hiding the identities of persons that followed them ...
